Yes, there are not any new interviews right now, but from time to time Eden will bring in people (authors, sex educators etc.) and we are able to ask them questions about their book, work, sexual questions that we may have etc. Eden will announce on the forums that they are bringing in the person to be interviewed and will ask us to welcome them to the community.
Currently, there aren't any active interviews. When the next one comes around, it will be announced on the forums. To ask your question then, you'd go to the "Interviews" tab (like the one above) and then select the current interview. You'll have the option of asking a question in that interview on that page.
